Trying to divide a string - php

Question

I am pulling information from my table. It is setup as a varchar. I can't change it because it 0's everything out when I do. I need to be able to divide the result by 12. It is the MY-TotalPrem that needs to be divided.
I tried
<td>'.$row["MS-TotalPrem" / 12].'
</td>, <td>'.$row["MS-TotalPrem"] / 12.'</td>,
<td>'.$row[int("MS-TotalPrem") / 12].
'</td>
and none work.
function fetch_customer_data($connect)
{
$query = "SELECT * FROM mytable";
$statement = $connect->prepare($query);
$statement->execute();
$result = $statement->fetchAll();
$output = '
<div class="table-responsive">
<table class="table table-striped table-bordered">
<tr>
<th>Name</th>
<th>Address</th>
<th>Address</th>
<th>Policy Number</th>
<th>Total Monthly</th>
<th>Expiration Date</th>
</tr>
';
foreach($result as $row)
{
$output .= '
<tr>
<td>'.$row["AC-AcctName"].'</td>
<td>'.$row["PM-PropertyAddr1"].'</td>
<td>'.$row["PO-Addr1"].'</td>
<td>'.$row["PO-PrefixPolNum"].'</td>
<td>'.$row["MS-TotalPrem"].'</td>
<td>'.$row["PO-ExpDate"].'</td>
</tr>
';
}
$output .= '
</table>
</div>
';
return $output;
}
I just want the output to be a division of 12, or any other number I put in. Thank you.
